PAUL E. HERRMANN, OF NEW YORK, N.

APPARATUS FOR HAIR WAVING.

Application filed February 27, 1923. Serial No. 621,571.

To all whom z'zf may concern.'

Be it known that I, PAUL E. HERRMANN, a citizen of the United States, residing at New York, iii the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Hair Waving, of which the following-ris a specification.

his invention relates to an apparatus for curling or waving hair and more particularly to an a paratus of the type described in my U. Letters Patent #1,199,-

550 in which the liquid or lotion required for the treatment is applied to an absorbent lining of shell of the ap aratus.

The main object of t is invention is to materially simplify the construction of the steaming device used in connection with said .apparatus and reduce the number of "-0 parts composing the same, so as, thereby, not only to lower the cost of manufacture but also reduce the weight and render the handling of the device comfortable.

Another object is to provide the apparatus with means for replenishing the liquid as the latter is being evaporated.

A still other object is to provide a shield or hair protector, whereby escaping steam will be prevented from scaldingthe head of the person treated.

And a further object is to provide a construction vin which the heater and steaming device are bodily combined to a single device.

With these and other objects in view, my invention consists in the novel construction, combination and arrangement of parts, as will be hereinafter more fully described and defined in the appended claims.

In the accompanying drawing, in which similar reference characters denote corresponding parts, Fig. 1 is a longitudinal. section of the. complete apparatus; Fig. 2`is a cross section on line 2 2 of Fig. 1; Fig. 3 is a cross section on line 3 3 of Fig. 1; Fig. 4 is a cross section on line 4 4 of Fig. 1; Fig. 5 is a longitudinal section of the rear end of the steaming device and of a modified stopper; Fig. 6 is a cross section on line 6 6 of Fig. 5; Fig. .7 is an end4 view of my im roved hair protector used in connection wit this apparatus; Fig. '7 is a cross section on line 7- of Fi -7 Fi 8 is a longitudinal section of the ront en of the steaming device with the modified shield applied thereto; Fig. 9 is a lon itudinal section of a modified steaming evice; Fig. 10 a cross section on line 10-10 of Fig. 9; Fig. 11 a perspective view of a detail of the steaming device; Fig. 12 is a sectional View of a steaming device with the heater directly formed thereon, Fig. 13 is a view similar to Fig. 7 showing a shield with modied locking means; Fig. 14 is a cross section of the steaming device showing means for tightening the forward end of the lining and Fig. 15 is alongitudinal section of the forward end of the steaming device, showing a modied construction of the tightening means.

The heating apparatus accordin to the construction shown in the patent a ove referred to, comprises a cylindrical casing a provided with a hollow handle b of heat insulating material, a tubular shell o centrally and longitudinally disposed in said casing and constituting with the latter an annular heating chamber containing an electric heating coil d, the terminals of which are connected with the wires e leading through said handle b.

The steaming device forming part of this invention, comprises a tubular member 10 of metal or other heat conducting material, which is formed with an inner. lining or shell 1-1 of suitable liquid absorbing material, such as asbestos or the like. This lining extends substantially throughout the length of the metal tube. 12 denotes a plate spring bent upon itself to form legs, and the latter are angularly bent substantially as shown. This spring is adapted to be placedin the tube 10, so that one of its legs extends between the asbestos shell or lining 11 and the other over the outer face of the tube. The bend 12 of the inner leg is adapted to spread the lining, so as to form a cavity 13 between the latter and the inner face of the tube' 10, for the purpose to be hereafter specified. The bends 122 in the outer leg serve as retaining members, and are adapted to frictionall en a e the inner wall of the rigid shel vc o t e heater, so as to hold the steaming device in position within the heater. The spring 12 may be secured in position on the tube 10 by a band 14 of asbestos or the like suitably attached to the tube. The absorbent lining 11 may be secured in position in the tube 10 by a spring coil 1 5 or the like mounted thereon and tending to hold it in frictional'" engagement with the wall of the tube 10.

The curler f, which may be of any suitable construction, such as the one shown in Fig. 8 and in my -patent above referred to, is adapted to be inserted into the tube to be surrounded by the lining 11 through one end thereof, after a lock or tress of hair is wound around it in the usual manner. The rear end of the tube 10 is adapted to be closed by a stopper g. The liquid which is poured into the tube or more correctly, into the shell 11, permeates into the cavity 13', which thus constitutes a reserve chamber. When the current is turned on, the heat generated in the chamber of the heater liberates steam or vapor from the lotion absorbed by the lining or shell, which acts on the hair producing the desired permanent curls or waves. The surplus liquid, which permeates into the cavity 13, will continue to feed the lining 11, as thev liquid in the latter evaporates.

Instead of using the solid ,stopper g, a hollow stop er or mouth piece 16 (Fig.4 5) may be use Thisvmouth piece is formed with perforations 16 and may be made to snugly fit ih the rear end of the tube 10 or shell 11. The outer end of the mouth piece may be closed by a cap- 17 threaded thereon. The mouth piece 16 is designed to serve as an auxiliary reserve tank, from which the liquid absorbed by the lining 11 will be replenished.

' A still other modification of the steaming apparatus is shown in Figs. 9-11. Here between the metal tube 10 and the, absorbent shell or sleeve 11, a feeder 18 is inserted. The latter consists of a rear hollow or. cup shaped mouth piece 19 and two lforwardly proJecting hollow arms or forks 20 communicating with the interior thereof. The cup 'shaped mouthpiece is adapted to fit more or lessloosely in the rear of 'the metal tube 10. Like the cup 16 shown in Fig. 5, the mouth piece 19 may ,be formed with perforations 19 opening into the annular space 10 between the tube 10 and said .,Qmouth piece and serving as passages for the f steam or vapor, as will be presently described. The rear end of-this cup is open' and adapted after filling the cup, to be closed by any suitable stopper such as 22. The arms or forks 20 projecting from the inner wall of the mouth pieces 19 are adapted to extend to the front end of the tube and except for a short distance near themouth piece are flattened or of substantially elliptical cross sec-tion with their inner facesl concaved as at v20. At their forward ends, there are a number of perforations, slits or recesses 202 inthe inner face of each fork (Figs. 10, 11). Fittedin the front end of the tube 10 between the latter and the absorbent shell 11 is a channelled ring member 23, so disposed as to engage the free ends of the forks 20. This ring is retained in its end position by the inwardly curved portion 102 of the tube 10. The forks 20 are so spaced apart that, when passed between the tube 10 and lining 11, the latter will be spread or compressed at two diametrically opposed sides, the flattened portions of said forks causing the compressed parts of the shell to form comparatively wide flues or passages 24 through which. the steam or vapor passing out from the arms 20 may flow back into the annular space 10 and thence reenter the mouth piece' 19 through the perforations 19' to mix with the lotion contained in said mouth piece. The curler f with the lock of hair wound around it is adapted to be inserted into the tube 10 through the front end thereof to be enveloped by the lining or shell 11. The liquid may be poured into the mouth piece 19, so as to cause it to pass through the openings 20 of the feeding arms 20 to the shell 11, which absorbs a part of it. After the insertion of the curler with the lock of hair wound around it, the steaming tubeis heated, as in the first case, whereby the liquid absorbed by the lining of shell will vaporize and act on the hair roducing the desired permanent wave. he steam or vapor will be allowed 'during the operation to continuously circulate through the lues 24, annular space 10', perforations 19', container 19 and feeding arms 20. The channelled ring in the front end of the tube serves to hold the ends of the forks 20, which are somewhat resilient, compressed against the lining, so as to frictionally engage the latter and hold it in position in the tube 10.

The apparatus may be still more simplified by utilizing the steaming tube 10 as part vof the heater.

To this end, a sleeve 25. of insulating material is fitted tightly over the rear end of the tube 10 and the electric coil 26 is wound around said sleeve. This coil is enclosed in a. cup shaped casing 27 havf ing central openings 27 27 2 to snugly engage the tube 10. The rear end wall 273 of the casing may be detachable to serve as a lid and may have suitably attached to it or formed integral with a handle 29 and with means (not shown) for attaching the wires to be connected to the coil 26.

The shield 30 used for protecting the head of the persontreated against the escaping vapor, and adapted to be placed at the front end of the apparatus, is usually made in form of al circular disc composed of two pivotally connectedsegments 30', 302, cut out in the center as 303 to engage the outer part of the `lock of hair to be treated. It has been found, howevenl that such construction-does not suiiiciently protect against the escaping vapors. To obviate this drawback, I provide each-section of the disc 30 with a marginal flange 31, so that when the sections are in closed position they will together form a cap, which with its open end will fit around the forward end of the tube 10, closing the latter more or less tightly as shown in Fig. 8.- As shown in Figs. 7 and 7, one of the sections, as 30', has fixed to its inner face an auxiliary plate 32 to form between itself and the body portion a sheath for the engagement of the other section in order that when closed, o pn crevices be avoided as much as poss1 e.

For holding the sections 3 0', 302 in closed position, they may be formed with suitable snap members, such as a depression 33 and a projection 34, shown in Fig. 7 or one section may be provided with a spring catch 35 and the other with a toothed or serrated ton ue 36 shown in Fig. 13. The .spring cate may have a pin 37 projecting through a perforation in the Harige of the corresponding section, whereby the same may be disengaged from the tongue 36, when the sections are to be swung open.

The escape of vapor from the steaming device may be effectively prevented by using means for tightly closing the forward end of the steaming device. Thus in Fig. 14, the forward end of the linin 11 may be tightened around the curler to Ive passed thereinto by a draw wire 38 or the like in a similar vmanner to a tobacco pouch. Or a band 39 of exible material, such as asbestos, -ma be suitably fastened around the forwar end of the steaming tube 10 to extend forwardly and equipped with a draw wire 38. similar to the one shown in Fig. vlet. By pulling the wire 38, either the lining or the band, as the case may be, will be tightly closed around the curler.
